Swedish dairy milk alternative Oatly has begun displaying the climate footprint of its product on all packaging to give consumers more information about the environmental impact. The company claims that its non-dairy beverage contains as much calcium as dairy milk, plus protein, carbs, unsaturated fats and “the beneficial properties of oats” – without the detrimental effects on the climate associated with milk production. The drink's carbon footprint will be presented using a number that defines its climate impact, expressed in carbon dioxide equivalents (CO2e). According to the company, swapping one liter of whole cow's milk for the equivalent measure of Oatly saves 1.16 k of CO2, the greenhouse gas equivalent of driving 10 km in an average gasoline-powered car.
